MECHANICAL OILER AN D JOURNAL-BOX FOR SHAFTING.

SPECIFICATION forming part of Letters Patent No. 333,950, dated January 5, 1886.

Renewed November 25, 1885.

Serial No. 183,944. (No model.)

To all whom it may concern:

Be it known that I, HENRY 1?. HUMPHREY, a citizen of the United States, residing at Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Mechanical Oilers and Journal-Boxes for Shafting, of which the following is a specification.

My invention relates to mechanical oilers IO andjournal-boxes; and iteonsistsin thehereinafter-described means of preventing dirt and lint from getting into such oilers and boxes, means of preventing the overflowing of the oil, means of connecting the nozzle of the oiler to the box, and to the construction of the parts.

In the accompanying drawings, on two sheets, Figure l is a front elevation of a part of a shaft and my improved oiler and journal-box secured thereto; Fig. 2, an end elevation of said. box and oiler; Fig. 3, a plan of the same; Fig. 4, an end elevation of the cam detached and its binding-wire; Fig. 5, a front elevation of the same, omitting one of 2 the wires; Fig. 6, a transverse section of the same on the line 00 a: in Fig. 5; Fig. 7, a central longitudinal section of the journal-box and cover; Fig. 8, a vertical transverse section of the journal-box, its cover, and the oiler 0 on the line y y in Fig. 1; Fig. 9, a vertical transverse section of said box and cover on the linez e in Fig. 7; Fig. 10, a central longitudinal section of the box, the cover being removed; Fig. 11,2. transverse section of the box without its cover on the line to w in Fig. 10; Fig. 12, a plan of the under side of the journal-box cover.

A is a horizontal shaft. 13 is thejournal-box proper, and B is its cover. The box B is in some respects similar to that shown in Letters Patent No. 309,954, granted to me December 30, 188-1, for mechanical oilers, in hav-- ing end drip-receivers, D D, an oil-reservoir, G, and a cored-out passage, F, to connect them with each other. The box is also provided with inclined grooves c c, which reach from near the middle of the box to the dripreceivers; but these grooves instead of being uncovered are in the inside of the walls of the box B, and are therefore not exposed to the lint and dust which may be floating in the air.

The cover B is, like the box B, preferably of cast-iron, and constructed with an oil-hole,

b, and on the inside with a chamber, [2 near the top of said cover, into which chamber said oil-hole leads. From this chamber oil-pas sages I) lead into the drip-receivers, which are continued around the shaft on the inside of the coverthat is, if we regard the cover as a part of the box, the drip-receivers are annular chambers formed in the inside of the box around the shaft near the ends of said box. Other oil-passages, b, lead from said chamber b in opposite directions and discharge at the side of said cover into the 6 grooves c c, the box being recessed at the top to admit the cover, as shown, the cover be- I ing prevented from moving endwise in the box bya lug, b on the side of the cover,which lug enters and fits anotch, b, in the box. The passages b I) are not grooves, but are cored out. The inside of the box B and cover B are lined with Babbitt or other antifriction metal or alloy between the drip-receivers only, the

outer side or ends, If, of the box not coming g in contact with the shaft. The chamber 1) reaches through the Babbitt metal to the shaft. Vhen the shaft is revolved, any surplus of the oil will be carried thereby in the direction in which the shaft revolves, and be driven partly through two of the passages If directly into the drip-receiver, the passages last named being inclined to the axis of the shaft, or through the passages 1) into the grooves c c, and thence into the drip-receivers, so that the chamber b and oil-hole cannot overflow and oil the outside of the box or cover.

The mechanical oiler or pump Kis substantially the same as that shown in Letters Patent No. 309,953, granted to me December 30, 0 1884, for mechanical oilers for bearings; but it is arranged wholly within the reservoir G, which is closed above the pump by a cap, G, struck up out of sheet metal and hinged on a horizontal stud, g, secured in a projection, g, cast on the reservoir. The pump K is secured in a bracket, I, as shown in the Letters Patent first-above named, said bracket having horizontal backwardly-extending forked arms or projections i t, the forks of which receive I00 the pump-barrel K, and there is a U-shaped strap, L, which clasps the barrel and holds it in said forks, the ends of said strap L being screw-threaded and extending through said bracket, where they are held by nuts ll, turning on them against the front of said bracket. The bracket I in this case, however, instead of being supported upon the outside and top of the reservoir, is wholly within the same, and has at top and bottom flanges z" i, which rest against the inside of the front of the reservoir G, and said bracket is held in place by a single screw, 4;, which passes through the front of said reservoir and into said bracket. Arranging the pump within the reservoir and closing the top of the reservoir prevents the dust in the air and the flyings of fibrous material in factories from getting into the reser- "oir and subsequently clogging the oil-passages,and from accumulating on the top of the pump. The outer end of the nozzle K does not reach into the oil-hole b, but is provided with a sleeve, K", which surrounds and slides freely on said outer end. This sleeve K fits the oil-hole b closely, and excludes dust and lint therefrom, and may be raised out of said oil-hole when it is desirable to see whether the pump is working satisfactorily, or to remove the cover B from the box B. Thelever M turns in a notch in the top of the side of the reservoirG, one end of said lever beingjointed to the top of the piston-rod, and the other being provided with an eye, at, into which a hook, it, on the upper end of the connecting-rod N catches. The lowerend of the connecting-rod is threaded and passes through alever, P, pivoted on a horizontal stud, g", secured to the projection g, and engages with a nut, n,which is prevented from accidentally turning by a flange, p, on saidlever. TheleverPis operated by acam, WV, which, instead of being a wiper, as shown in said patent, is substantially an eccentric on the shaft. The cam Wis made from a strip of metal, preferably wrought-iron or steel, long enough to go about half-way around the shaft, is scarfed down to an edge at each end, and has longitudinal grooves 11 v milled in the same near its edges, the strip being scarfed only between the grooves. The strip is then bent into a halfcircle with the grooves '12 t on the outside, andis applied to the shaft, and held in place by wires 4/ 'u, surrounding the cam and shaft and laid within the grooves 11 v, the ends of the wires being unitedby twisting them together, as shown in Figs. 4, 5, and 6.

The above-described construction and means of attachment ofthe cam W is inexpensive and effectual, and allows of the cam being readily attached to and detached from the shaft at any point. The greatest thickness of the cam need not exceed a sixteenth of an inch in ordinary cases.

To prevent the wear of the cam WV and lever P on each other, I cover the top of said lever where it touches the cam with astrip of leatheroid, p. This substance is superior to metals, because the friction is less, and it is superior to rawhide, because it is not softened by oil.

I claim as my invention 1. The journal-box proper, provided with end drip-receivers, inclined grooves on the inside of'said box near the top of the same and leading from points about midway between the ends of said box into said drip-receivers. the cover having a chamber on the inside of the top of the same, an oil-hole leading through the top of said cover into said chamber, and oilpassages leading from said chamber int-o said inclined grooves, as and for the purpose specified.

2. The combination of the box proper pro- Vided wizh end dripreceivers, and the cover having a chamber in the inside of the top of the same, an oil-hole leading through said cover into said chamber, and oil-passages cored out in said cover and leading from said chamberinto said drip-receivers, as and for thepurpose specified.

3. The combination of the box, its cover having an oil-hole communicating with theinterior of said cover and box, the pump having a nozzle, the free end of which extends over said oil-hole, and a sleeve surrounding said free end of said nozzle and sliding freely thereon and adapted to enter said oil-hole and fit the same, as and for the purpose specified.

4. The cam or eccentric provided near its side edges with grooves and adapted to be wrapped partly around a shaft and to be held thereon by Wires laid in said grooves and fastened around said shaft, as and for the purpose specified.

5. The cam or eccentric formed of astrip of metal, provided near its side edges with grooves, and scarfed at each end to an edge between said grooves, and adapted to be Wrapped partly around a shaft and tube held thereon by wires laid in said grooves and fastened around said shaft, as and for the purpose specified.
